Wi‑Fi Not Connecting? 2.4GHz vs 5GHz, WPS, and Wi‑Fi Direct

Printers often only support 2.4GHz Wi‑Fi or struggle with DFS channels on 5GHz. Start with band checks, then try WPS/manual SSID, or use Wi‑Fi Direct.

1) Verify Wi‑Fi band and SSID

• Legacy printers may not see 5GHz; use 2.4GHz SSID.
• Disable DFS channels; prefer channels 1/6/11 for 2.4GHz.
• Check for AP isolation and MAC filtering on the router.

2) Use WPS or manual SSID

• WPS: Press printer Wi‑Fi/WPS → press router WPS within 2 minutes.
• Manual: Control panel → Wireless Setup → select SSID → enter password carefully (case‑sensitive).

3) Try Wi‑Fi Direct (ad‑hoc)

Enable Wi‑Fi Direct on the printer and join the temporary SSID from your device. Good for quick prints or initial setup.

4) Reserve a static IP

In your router, reserve the current printer IP to its MAC address. Prevents “Offline” after reboots.
